FORGING-JPROOF DROP-STOPPER.

To all whom it may concern: Be it known that I, EMILE ALLIIt, a citizen of the French Republic, residing at Paris, 4. Rue Meslay, France, have invented new and useful Improvements in Forcing- Proof Drop-Stoppers, of which the followin is a full and concise description.

1 y invention refers to forcing-proof dropstoppers and its object is to prevent fraud by obviating the introduction of any for eign matter into recipients intended to contain a special product or a product of a particular brand.

I attain these objects by the mechanism illustrated in the accompanying drawings,in which:

Figure 1 is a vertical section of a dr0pstopper when closed or at rest.

Fig. 2 is a vertical section of the same apparatus turned upside down.

Fig. 3 is another constructional form of the drop stopper, and

Fig. 4c a top view of the star-branched piston shown in Fig. 3.

Similar letters refer to similar parts throughout the several views.

A cylindrical body 1 (to be placed as an ordinary stopper within the neck of a receptacle) is covered with cork stufi or other convenient material so as to render leaking impossible. A hollow crown 2 surmounts the cylinder and keeps the apparatus in place above the neck of the receptacle. In the top of the hollow crown 2 slides a hat 3; the lower portion of this hat is formed of a sort of a three (or more) branched cage,

I each of these branches ending in a projection 5 of which the function is to close the double valve 6 when the receptacle is in its normal position that is to say standing; the open interstice between the branches 5 allow the admitted liquid to flow out freely when the receptacle is shaken or turned downward.

The support 7 keeps back the valve 6 when the receptacle is quite or partly turned downward that is each time when being used; as soon as the receptacle is put in an upright or standing position, the valve 6 comes to rest on the seat 8 at the bottom.

The bottom part 10 of the cylindrical body is suitably perforated at 10 so as to allow tlopics of this patent may be obtained for five cents each, by addressing the Serial No. 747,165.

the liquid to flow into the stopper casing as soon as turned downward; on the center of the cylinder bottom projects a knob 11 upon which slides freely the said double valve guided by its cylindrical hole 12.

Fig. 3 represents another constructional form of the forcing-proof drop-stopper, in which form a double valve 6 guided by a knob 11 and coming alternately to rest on the two seats 7 and 8 is operated by a star (four or more) branched piston 13. A wire netting or a metallic sieve 14: may be inserted zjvighin the top portion of the cylindrical In this constructional form the cap 3 is removable and has to be removed when the drop-stopper is to be used.

I. am aware that prior to my invention forcing-proof drop-stoppers have been made with movable valves in conjunction with other movable members.

I therefore do not claim such a combination broadly; but what I do claim as my invention, and desire to secure by Letters Patent is:

1. In a forcing-proof drop-stopper: a cylindrical body with suitable perforations in its bottom, a hollow crown on top of the said cylindrical body, within said hollow crown a movable cap with a three or more times branched lower portion terminating in projections for driving downward a double valve guided inside the said cylindrical body by a knob, and an upper and a lower seat within the said cylindrical body for the said double valve, substantially as set forth.

2. In a forcing-proof drop-stopper a cylindrical body with suitable perforations in its bottom and a removable cap on top of it; a double closing valve guided, within the cylindrical body, by a knob, two seats for the said double valve and a star branched piston for driving downward the said double closing valve, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EMILE ALLIE.
